Hello
welcome to health care magic
You should not start worrying there is a solution for every issue and I will try to help you out in best possible way.
Looking at your description I would advise you for a battry of tests like
stool test for ova,cyst or protozoa .
you may require a course of antibiotics like
ofloxacin or
ornidazole group of drugs depending upon the stool test report.
Meanwhile I would advise you to use anaesthetic ointment like lignocaine before or after going to stool in oreder to reduce itching and pain.
maintain good hygiene, have plenty of fluids orally.
Have lots of fresh fruits and vegetables as well as dietary fibers in your diet.
you can take sitz bath for early recovery and symptomatic relief.
Antiacidity medicine like
pantoprazole or
ranitidine group of drugs are also advisable.
Hope this answers your question, thanks for writing to us.
Best wishes
